Title: Trueing device for grinding wheels
Inventor: ROHRLE ANTON
IPC: B24B53/00
Filed: 1970-02-03
Abstract: 1298761 Trueing grinding wheels LOHF & TILLIPAUL 3 Feb 1970 [3 Feb 1969] 5127/70 Heading B3D  A trueing device for a grinding wheel comprises a carrier 4 rotatable to limits determined by adjustable stops 7, a slide guide 11 extending at right angles to the axis of rotation of the carrier, a slide 12 carrying a trueing tool 14 and movable along the guide, a slider 15 connected to the slide by adjusting screws 22 and having abutment surfaces 16 at its ends a distance apart corresponding to the distance apart of abutment surface 17 on the slide guide 11, the surfaces being engaged by elements 20 connected to a tension spring 19 to resiliently hold the slide in a mid position, and a driving device having a shaft 26 coaxial with the carrier to effect rotation of the carrier to the limits determined by the stops and then via members 28, 29, 30 effect linear movement of the slide against the action of the spring 19. The carrier 4 is rotatably mounted in a sleeve 3 in a housing 2 carried by a base-plate 1, the movement of rotation being limited by the stops 7 in the form of screws adjustable in a T-slot 5 and cooperating with a stop fixed to the housing 2. The slide guide 11 is secured to the carrier 4 and slidably receives the slide 12 which is joined to an arm 13 carrying one or more trueing tools 1, 4, such as coarse and fine trueing tools. The slider 15 is secured to the slide 12 by the screws 22 and is guided in a slot 25 in the guide 11. A recess 18 in the slider accommodates the tension spring 19 which, at each end, is connected to an element 20 in the form of a pin. The slide 15 and guide 11 are equal in length so that, in the mid position of the slide, the pins engage the abutment surfaces 16, 17 of both the slider and guide; the mid position of the slide can be adjusted by the screws 22. The driving shaft 26 is rotatable in the carrier by a crank 27 and has a half gear 28 which engages one or other of racks 29, 30 connected to the slider; the shaft 26 is coaxially movable to permit selection engagement of the gear 28 with rack 29 or 30. In operation, rotation of the crank rotates the carrier to move the trueing tool in a circular path until rotation is prevented by engagement of the stops, further rotation of the crank causing movement of the slide 12 and slider, and hence linear movement of the trueing tool, against the action of the spring 19.

Title: Improved method of mounting a journal bearing
IPC: F16C35/067
Filed: 1959-02-20
Abstract: 906,105. Supporting and mounting bearings. PITNER, A., and ROULEMENTS A AIGUILLERS S.A. DES. Feb. 20, 1959 [Feb. 21, 1958], No. 5887/59. Class 12 (1). [Also in Group XXIV] In a method of mounting a bearing R, Fig. 4, in the housing 1 of a member P and around a journal T whose axial position relative to the member P must be obtained within a specified tolerance, a supporting face 9 is provided in the member P and is situated a known axial distance from the housing 1, and the bearing, having a face 8, axially abuts an end face 7 of the journal T and, while the journal and member P are maintained in their final relative position, a dish-like member E is deformed so that it is trapped between the supporting face 9 and the bearing R and so holds the latter against the journal T. The member E is made from ductile material and is deformed by a roller &c. 17 so that it extends to the face 9 and serves as an abutment member between the member P and the bearing R. In a modification, Fig. 5, the member E<SP>1</SP> solely abuts the journal T<SP>1</SP> and the bearing 5a holds a seal 21 against a shoulder 21a on the journal T<SP>1</SP>. In another arrangement, the member E has curved ends which are forced open and enter recesses in the member P; alternatively, the member E is castellated or consists of a number of pieces. During the deformation of the member E, the member P and/or the member T are also deformed, e.g. by pressure or heat, in order to provide clearance between the axial abutment faces. In another embodiment, Fig. 9, applied to a Cardan joint, the joint has four journals T incorporating the above method of mounting. Each journal is held in a branch of a fork M<SP>1</SP> or M<SP>2</SP> which corresponds to the member P in Fig. 4 and each branch is temporarily deformed by a lever 30 pivotably mounted at 31 in a recess 32 in a plate 25. The lever 30, having a circular shoulder 33, bears against the branch of the fork, and at the opposite end of the lever a stud 34 is adjusted to engage a cam 35, which being screw-threaded on to a spigot 36 on the plate 25, is screwed inwards to deform the fork-branch. At this stage the member E is deformed by the roller 17, which is applied through an aperture 33a in the lever 30.

Abstract: 223,489. Soc. l'Air Liquide, Soc. Anon. pour l'Etude et l'Exploitation des ProcÚdÚs G. Claude. Nov. 20, 1923, [Convention date]. Separating gaseous mixtures by liquefaction.- Ethylene is removed from illuminating or like gas which is to be partially liquefied and rectified, by circulating the gas upwardly in a temperature exchanger through the zone in which ethylene liquefies and up to the zone where considerable liquefaction of methane takes place, the ethylene being progressively liquefied, and the methane in the liquid so formed being vaporized by allowing it to flow back to a collector from which the liquid containing ethylene together with ethane, acetylene, &c is extracted. The apparatus shown comprises three heat exchangers A, B, C through which the separated hydrogen passes reversely through pipes 1, 5, 9, escaping by the outlet 15, and carbon monoxide and methane similarly pass through pipes 2, 6, 10 to the outlet 16. The gas to be purified passes through pipes 11 - - 14 to the separator. Readily liquefied impurities may be drawn off from the exchanger A by taps, as described in Specification 195,598. Ethane is liquefied in the exchanger B and flows d.own to a collector K from which it is withdrawn. Several collectors K may be provided at different heights, the most suitable being employed. The carbon monoxide and methane which are not so cold as the hydrogen may be introduced directly through the pipe 5.

Abstract: 339,885. Humphreys & Glasgow, Ltd., (Assignees of Haug, J. S.). May 6, 1929, [Convention date]. Water-gas plant.-In apparatus for cooling gas such as carburetted water gas, a relief holder is connected to a point intermediate of the inlet and outlet connections of a condensing chamber, the cooling agent passing through the latter in counter-current to the gas flow. The hot gases enter the condenser 1 at inlet 2 and are cooled by water flowing through the tubes 5 which terminate in the upper and lower tube sheets 6 and 7 respectively. The condenser is divided into passes by partitions 4 and communicates with the relief holder 14 by the connection 12. Excess gas traversing the condenser passes to the relief holder. A deficient gas supply for the exhausters may be supplemented by gas drawn from the relief holder. In a modification, the holder communicates with a connection betweem two condensers and two valved connections may replace the connection 12.

Abstract: 674,926. Cathode-ray tubes. RADIO CORPORATION OF AMERICA. Feb. 27, 1948 [Aug. 30, 1946], No. 6133/48. Class 39 (i). A memory tube as described in Specification 674,925 has the control grid connections modified so that only two grid networks are, required for control of as many as one million memory elements. In one form, Fig. 1, a " group of one " system of connections is used, i.e. each set of grid wires is connected to a single group of leads, for example as shown by the heavy dots. Each pair of leads is thus connected to only one pair of adjacent grid wires, so that individual control over every grid "window" obtains. There are n leads and n(n-1)/2 grid spaces in each network (n is odd). In the other form, Fig. 2, useful for decimal system computers, each set of grid wires is connected to two equal or unequal groups of leads a, b so that a+b leads control a X b grid spaces. In both forms the sets of grid wires may be horizontal and vertical in a flat or cylindrical segment or cylindrical electrode arrangement, or may be concentric helices 17, 23, Fig. 4, wound in opposite directions. The helices 17, 23 are carried in mica supports 19, 21. The target 25 may fluoresce as well as serve for memory storage. The leads are all taken out at one end of glass envelope 27. The Specification as open to inspection under Sect. 91, states that in the Group of one system of connections, n may be even. The memory screen may be replaced by a fluorescent screen. This subject-matter does not appear in the Specification as accepted.
